Byebug install error #280

katawura · 2016-07-03T00:20:14Z

l am currently trying to install byebug with my rails project and keep getting this error

An error occurred while installing byebug (9.0.5), and Bundler cannot continue.
Make sure that `gem install byebug -v '9.0.5'` succeeds before bundling.

Any idea why this would be?

The text was updated successfully, but these errors were encountered:

@katawura please include compilation log.

Same issue for me...

@notcreativeusername can you please include /Users/myid/.rvm/gems/ruby-2.2.4/extensions/x86_64-darwin-15/2.2.0/byebug-9.0.5/gem_make.out here ?

notcreativeusername · 2016-09-29T16:35:59Z

Not sure it will help much.... and FYI to get around this error I ran sudo gem install byebug -v '9.0.5' and it didn't throw this error. Not ideal but it works.

Looks like it only happens on Mac OS.

So sudo gem install byebug -v '9.0.5' successfully compiled byebug?

dmitry · 2016-09-29T17:03:40Z

sudo which gcc and which gcc have the same paths?

notcreativeusername · 2016-09-29T17:09:49Z

looks like it installed ok

dmitry · 2016-09-29T17:15:15Z

I'm not a Mac user, but looks like the only solution is to use:

CC=llvm-gcc gem install byebug -v '9.0.5'

notcreativeusername · 2016-09-29T17:18:45Z

I tried that before and it didn't work unless I typed something wrong.....

deivid-rodriguez · 2016-09-29T17:24:31Z

Try a clean install of another ruby. If that works I think this is a problem with your current ruby. If it doesn't it might be a problem in byebug. For example,

rvm install 2.2.5
rvm use 2.2.5
gem install byebug

Speaking from memory since I don't use rvm.

deivid-rodriguez · 2016-10-09T22:44:27Z

@notcreativeusername anything?

harishsr · 2017-12-08T18:43:14Z

I had the same problem. Installing XCode Command Line Tools fixed it.

deivid-rodriguez · 2017-12-08T22:55:15Z

Closing since it's an old issue probably unrelated to byebug, thanks for the feedback!

ljromero · 2018-09-19T12:03:23Z

Confirmed @deivid-rodriguez! Upgrading rvm fixes this issue.

I can confirm it is not working on Ruby 3.0.1 running on Apple M1, macOS 11.5.2

tubsandcans · 2021-09-16T20:35:54Z

I'm also unable to install this extension (or sqlite3 1.4.2) using Ruby 3.0.0 or 3.0.2 on macOS (Intel) 11.5.2.

timtim22 · 2021-10-22T13:45:18Z

guys, any update on this? I am also not able to install it on Apple M1, Big Sur

mbpod10 · 2021-10-25T18:40:40Z

I am also having issues, running Big Sur. Same problem as above.

jaw6 · 2021-10-30T16:22:45Z

I definitely don't have this 100% but in case this is useful to someone else, here's what I did to get this working.

Background: I have an Intel MacBookPro on Catalina (10.15.7).

I was getting the above error message and the messages seemed to be coming from C, which made me think it could be a C-compiler problem.

So, with homebrew, I was able to install a newer clang/llvm:

brew install llvm

And then use it:

export CC=/usr/local/opt/llvm/bin/clang

After this I was able to install byebug. I'm not aware of anything else I did, so I think this made the difference.

In case it's helpful, here are the versions of clang before/after:

❯ /usr/bin/clang -v
Apple clang version 11.0.3 (clang-1103.0.32.62)
Target: x86_64-apple-darwin19.6.0
Thread model: posix
InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

❯ /usr/local/opt/llvm/bin/clang -v
Homebrew clang version 13.0.0
Target: x86_64-apple-darwin19.6.0
Thread model: posix
InstalledDir: /usr/local/opt/llvm/bin

cheradenine · 2021-11-07T00:52:18Z

This might help - have not tried it yet to confirm..

#825 comment 903260365

ronaldtse · 2021-12-22T00:22:53Z

I also encountered this error (Apple M1, Monterey), and it worked after setting export CC=clang.

cyangOL · 2022-01-08T05:06:53Z

I got it working with below steps on big sur:
Reinstall commandline tools

sudo rm -rf /Library/Developer/CommandLineTools
xcode-select --install

Install llvm

brew install llvm

Set cc and ccx to llvm from homebrew
export CC=/usr/local/opt/llvm/bin/clang
export CCX=/usr/local/opt/llvm/bin/clang

akahn · 2022-04-12T17:54:25Z

Thank you. This solution worked for me. However, on my setup, Homebrew installed the clang executable in a different directory, and it was only necessary to set CC. So, for me, this was enough:

brew install llvm
export CC=/opt/homebrew/opt/llvm/bin/clang

dmlo · 2022-06-15T18:27:07Z

For the people coming here from search engines... Installing older versions of byebug (in my case, 4.0.5) required the installation of llvm@11 and then

export CC=/usr/local/opt/llvm@11/bin/clang
export CCX=/usr/local/opt/llvm@11/bin/clang

Oh, the joys of legacy development.

bbulpett · 2023-04-25T18:50:58Z

Using Ventura, I had the same issue and tried the above solutions. I tried them in the embedded IDE terminal (vs code) and gem install showed same error - even when restarting embedded terminal. Then I switched to the OG mac terminal app and gem install byebug and subsequent bundle install completed without issue.

patbl · 2024-06-18T19:01:36Z

I get an error when I try to install llvm@11:

$ brew install llvm@11
Error: llvm@11 has been disabled because it is a versioned formula!

But the following worked for me on Sonoma 14.5 and Ruby 3.0.5:

brew install llvm@12
export CC=/usr/local/opt/llvm@12/bin/clang # Edit: better is `export CC=$(brew --prefix llvm@12)/bin/clang`; see next comment
gem install byebug -v '9.0.6'

llvm@16 did not work. I'm not sure at which point between 12 and 16 this broke.

ishan123456789 · 2024-06-29T20:28:02Z

adapted answer if your address for brew packages is different:

brew install llvm@12
export CC=$(brew --prefix llvm@12)/bin/clang
gem install byebug -v '9.0.6'
